TR6 Fixing the intake manifold

[steveg]

Is there anyone out there who can shape the intake manifold better? Or is there any info on doing it yourself.

This looks like it could use some work ('74 TR6):

A little re-shaping probably can't hurt.

Dremel and carbide bit? I think the Kastner race prep book gives some information on this http://www.kaskastner.com/kasbooks.html you find hard copy on ebay as well

A die grinder with a carbide burr makes very quick work of matching ports. You can finish up with a flapper wheel or sanding roll. Most are available from welding or nut and bolt supplies. The die grinder can be found at Harbor Freight or Northern Tool. Of course you'll need an air compressor.

I like rotary files and dermal stones for smoothing. The rotary files in a cordless drill because the files are aggressive and the stones in a die grinder for the high RPM and smoothness.

Glemon - thank you for this link. I bought the pdf and had it double-sided printed and wire bound. A comprehensive resource!

I've done the dremel and drill routines. They will work, but will take at least 30 minutes time for the same amount of metal removal as just 1 minute with an air powered die grinder and a carbide burr.

Took about an hour to get both ports to this point using the burr below:





Have ordered a 6" burr to reach farther in from both ends.
